rUNeTUnn-Pnoor TIRE.

To all whom it may'conceynb S Be it-ki1own that I, RiciiAnn B. Hams,- a citizen of the United States, residing at Lawrence, in the county of Douglas and State of Kansas, have invented certain new and. useful- Improvements in Puncture- Proof Tires, of which the following a specification This invention comprehends certain new and useful improvements in puncture-proof tiresiand has for its primary object to provide a tire of this character. including apneumatic tire and protecting means pos1- tioned upon the'tread portion of said pneu- 5 matic tire to prevent puncture of the same.

Another object of this invention is to provide a double puncture-proof tire which will be of simple construction and operation as well as durable and formed in such manner 0 that independent lateral movement of the outer protecting casing or covering will be;

prevented. Another object of the invention is toprovide atire-of this character which will be 55 formed in such manner that the parts thereof will interlock and may be readily se- 'cured together to prevent disengagement of the outer members from the pneumatic tire. This invention has for a further object to 50 provide a puncture-proof tire of this character which will be of simple construction as wellas strong'and durable and highly I eflicient in use. 1 With these and other objects in View as will become more apparent as the description proceeds, the invention consists'in certain novel features of construction, com- I bination and arrangement of parts as will be hereinafter more fully described and claimed.

' For a complete understanding of my invention', reference is to be had to the fol-- lowing description and accompanying drawings, in which I Figure 1 is a fragmentary side elevation of a puncture-proof tire constructed in ac-., r weordance with my invention, Fig. Zis a longitudinal section through the same, F g. 3-

is a transverse section on line 3-3 of Fig. 2,

with the parts slightly enlarged, Fig. 4 is a fragmentary bottom plan View of the outer protecting casing or cover removed, and Fig. 5. is a fragmentary side elevation of the pneumatic tire and annular flange carried thereby,

numerals, '1 designatesa hub, 2 the spokes,

and 3 the felly of a wheel withwhich my improved puncture-proof tire may be employed, the pneumatic tire 4 being positioned in the telly 3 and having spaced continuous flanges 5 around its opposite outer edges to receive the continuous side flanges 6 formed at the lower edges of the outer or protecting casing? and upon the "outer face of the same, as will be readily understood by referring-to the'drawingsfl- Clhe flanges .5 are provided at spaced distances with outwardly directed ears 8 which register with the corresponding outwardly directed ears 9 carried by the flanges 6, and said ears 8 and 9 are provided with threaded apertures through'which the set screws 10 are engaged to securely fasten the outer protecting cover '7 upon the pneumatic tire 4:.

The pneumatic t re 4 has an annular flange 11 mounted upon its tread portion and. provided at spaced distances with notches 12 in its outer edge within which are engaged the transverse spaced cushionblocks 13 which have extended end portions 14 which are engaged upon opposite sides of said annular flange 11 when said-blocks 13' are in position in the notches 12, thereby preventing independent lateral movement of the outer protecting casing or cover 7, as

*well as making it impossible for said outer cover or casing 7 to move longitudinally upon the flange 11. It will further be seen that the flange 11 and cushion blocks 13 serve to space the main portion of said outer protecting casing or cover 7 from the fpneumatic tire 4 and 'form cushioning members, thereby lending more resiliency to the tire.

) It will also be readily understood that the outer-portion of the casing or cover 7 forms the tread of the device, andthe blocks 13 and flange 11 will prevent any sharp pointed article from reaching thepneumati'c tire' i:

and therebypuncturing the same;

From the foregoing it will be readily seen that I have provided a puncture-proof tire which will be of extremely simple construc- 1 tion and cheap to manufacture as well as highly efficient and resilient in use. It-willbe understood that the-protector 7 is flexible so that it yields locally.

While the preferred embodiment of my in? vention. has been shown, it will be under stood that minor changes in the details of and upon the outerface of the tire, oppoconstruction, and arrangement of parts may be made within thescope of the appended claims without departing from thespirit of my invention or sacrificing any of the advantages thereof. 1

What -is claimed is 1. A device of the class described comprising a pneumatic tire, a pair of strips secured longitudinally to the Opposite sides thereof sitely directed ears projecting from said strips, an outer protecting casingresting upon said tire and having strips secured to its' lower longitudinal edges and resting the'combination with a tire; of strips secured to the outer face thereof at its oppo'sitesides, ears projecting outwardly from i upon the first mentioned strips, ears projecting. outwardly from the second mentioned strips and resting upon the first mentioned ears, said first and second mentioned ears being provided with registering openings, means threaded in said registering openings to secure the casin in position, said casing being formed of exible material to yield 136 upon the first mentioned strips, ears directed "locally, and cushioning and reinforcing outwardly from the. second mentioned strips and resting upon the first mentioned ears means--secured--through the first mentioned Qand second mentioned ears to secure the Zflji'casing in proper position and prevent the "same from creeping upon the tire, and Spaming and cushioning means positioned between the tire and the central portion of the casing.

2. A device of the class describedcomprismembers carried by the tire and casing and interlockdwith one another and serving to space the main portion of the casingfrom the tire. 1
